create voronoi polygons in a loop

hi there,

I have a question regarding loops in FME and my inputs are:

A point file(have an ID field) and polygon file (have an ID field).

Now I want to create voronoi polygons from point file but in a loop in which I will select first polygon and all points in side it, create voronoi polygons, clip voronoi polygons with selected polygon and save the result.

Then loop goes to second feature and same procedure runs till the end of polygon file.

In this way my voronoi polygons will be seamless with input polygon layers which is for me very important.

This is first time I am doing something in FME with some loops. I have searched and sofar, I have not found any thing which can help me. so l am looking for some suggestion.

Why not use a spatialRelator on your points to assign the polygonID to them, and then use that ID as Group By on the VoronoiDiagrammer and also on the clipper.

Hi, I have the same issue.

I want to create voronoi Polygons (Node Areas) within municipalities borders. The point file contains attributes like de NODE_ID. The municipality file contain a ESRI_ID which is not sequence in order.

Remark:

It is strictly undesired to have polygons representing Node Areas within the limits of a municipality that do not contain at least one building with the related Node ID.

How do I assign the two ID fields in the SpatialRelator?
